    FCC OET authorization documents are not required to disclose downlink CA. Accurate info on that capability is hit or miss. AJ

    T-Mobile has more QAMs for stronger Hzs, faster dBms, and better GBs. AJ

    The worst part about Sprint? Many current or former Sprint users. Every day with them is like the first day of Festivus. The Airing of Grievances 365 days a year. AJ
  4. WiWavelength
    No, not necessarily. The opposite can be true. Less ground clutter to block or attenuate signal between sites can mean more interference between sites. AJ
  5. WiWavelength
    Yes, it was an amazing response. I detected exactly what Brynn0823 was thinking. See his reply. AJ

    I suspect that he is referring to the character flaw chronic among former Sprint users who feel the need to stick around Sprint discussion and repeatedly tell how Sprint has disappointed them. Other people move on with their lives and interests. AJ

    Every two child did. I will. AJ

    No. The SoC, which contains the baseband modem, is not the end all, be all determining factor for certain RF capabilities. Other pieces have to fall into place as well. That a baseband supports a certain RF capability assures nothing in terms of actual implementation. AJ

    In a typical Sprint market, band 41 utilization almost certainly will be greater than 256-QAM utilization. Band 41 may have a "short umbrella" in the macro environment compared to that of band 25 and band 26. However, the 256-QAM umbrella will be even shorter, significantly so. AJ

    The T-Mobile 4x2 MIMO sites always have been 4x4 MIMO capable. Both it and higher order modulation are just software upgrades, hardly heavy lifting. T-Mobile simply was waiting for compatible devices. How beneficial 4x4 MIMO and higher order modulation will be, though, is questionable. We need to see stats on real world utilization rates. AJ

    Yes. And people who are eating up this T-Mobile announcement are buying into smoke and mirrors. Both 256-QAM and 64-QAM utilization almost certainly will be under 10 percent of the time. A great comparison is my cable modem downlink, since it uses 256-QAM 100 percent of the time. But that is over a shielded coaxial cable, and my received downlink signal is a fairly consistent -70 dBm with a 33 dB SINR. How often is that signal level and quality available in the macro RF environment? Now, look at the flip side, my cable modem uplink modulation is QPSK or 64-QAM. For the sake of argument, we will look only at 64-QAM, the higher order of the two. My cable modem uplink Tx power is a largely stable 46 dBm. Compare that to a handset uplink Tx power that typically maxes out no greater than 23 dBm -- about 200 times lower power. You know, people criticize Sprint because they are not on band 41 often enough to their liking. Well, T-Mobile users are going to be utilizing 256-QAM and 64-QAM far less often than that. However, adaptive modulation lurks underneath the hood, while band selection is more visible to end users. So, people will be oblivious to the fact they are rarely, if ever actually using 256-QAM and 64-QAM. They just see the announcement of higher peak speeds and think, "Ooh, new, shiny." AJ

    A no greater than 5-10 minute read through this thread would have shown that others are not experiencing even remotely the same signal/reception issues. As such, the separate threads here and at Reddit still seem unnecessary. I am sorry for your trouble. But the problem is between you and Huawei. You seem determined to raise a stink in public. Is that an effort to shame Huawei into covering the issue under warranty? As long as you or someone else did not cause damage to the handset during the first 30 days that you are trying to pass off as a defect, then, agreed, Huawei should honor its warranty. However, S4GRU is not party to this dispute, and just as S4GRU does not host Sprint complaints, I am not sure that we want to host Huawei complaints either. AJ

    No, not really. Folks, coverage is service -- defined as a functioning uplink and downlink. Performance is a different matter. Now, while in an active data session, CA may be able to expand band 41 coverage by extending band 41 cell edge. But it cannot expand coverage "beyond" cell edge. That would be akin to inflating a balloon beyond its bladder. Additionally, CA is unlikely to expand overall Sprint coverage -- unless only band 41 is available, no other bands are available. AJ

    I am unsure why a post, let alone a new thread was necessary. MrZorbatron seems already to have come to the supported conclusion that this particular unit is defective or damaged. Do not make a fuss about it -- just return or exchange the unit. If it cannot be returned or exchanged, caveat emptor. AJ

    Use your brain -- not your heart or stomach or e-penis. How is that "unlimited" data working out for everyone? A lot of people complain about slow speeds and network congestion, while a few people use/abuse a hugely disproportionate percentage of network resources. Tragedy of the Commons. Consumer self interest leads to consumer harm to all. AJ
  16. WiWavelength
    And uplink CA -- aka ULCA Bruins -- will not make coverage matters any better. We like to see a max EIRP of 23 dBm or greater on band 41. But almost no chance will uplink CA pump out 23 dBm or max EIRP on each of two carriers. I fully expect optional or mandatory power reduction to be implemented if ever uplink CA is active. Got to conserve that mobile battery life and suppress RF intermodulation products. AJ
  17. WiWavelength
    Yes, but... Performance ≠ Coverage AJ

    Sprint is willing to strike a non monetary deal with you to pay off your debt. Sprint has a surplus of Samsung Galaxy Nexus. To eradicate the old inventory, that is the only handset model your entire account may use from here to eternity. AJ
  19. WiWavelength
    You broke it, you bought it. PythonFanTN, you now owe Sprint eleventy billion dollars. AJ

    Uh, there you are. Yeah, I spotted you right over there. AJ

    Substitute Las Vegas for Phoenix. AJ

    Letting PCS G speak for itself. PCS B, too. AJ

    Actually, the term you are looking for is "paranoid crazy." Both of these members probably drive the Lux 420SL. http://www.nbc.com/saturday-night-live/video/lux-420sl/n10918 AJ

    I would have to double check, but I do not believe that LTE uses closed loop power control on the downlink. In other words, no power boost just because the uplink is on a lower band and does not fail for a greater attenuation/distance. The reference signals certainly are fixed ERP/EIRP. AJ
